From the Facebook group God is Open:

What’s the difference between a God who foreknows evil will exist but still creates vs a God who currently allows evil to exist and lets it run rampant?

It seems to me that consistent open theists would be atheists. If you’re repulsed by the idea that God foresees and allows evil, which you describe as God desiring the development of sin and wickedness, then it would be consistent to also be repulsed by the idea that God currently desires the presence of sin and wickedness.

Christopher Fisher responds:

Is there a difference in your mind between seeing evil and not stopping it and doing actions that have no alternative but to result in evil?

Sometimes as a parent I see my children fighting, sometimes physically. Would a benevolent parent always intervene? I know sometimes, I let it go. Does that mean I approve of physical violence? Does that make me not “benevolent”. Myself, I do not see inaction as “not caring” or “not loving”. I believe the same concept applies with God.

…but another interesting thing to note is that we have examples in the Bible of God killing people because they were so evil. In the closed world view, this makes no sense. Why didn’t God kill them before they became so wicked to make Him kill them? Why wait until after the evil has happened? The fact that God steps in from time to time to stop evil proves the future is open.
